丁酸通过增强肝线粒体功能缓解高脂诱导的小鼠肥胖北大核心CSCD

丁酸可以预防高脂日粮诱导的小鼠肥胖和胰岛素抵抗,但是否有治疗作用尚不清楚。本研究证明,高脂日粮诱导小鼠肥胖模型后,用80 mg/mL丁酸钠水溶液灌胃能够缓解肥胖。表观指标检测发现,丁酸钠显著降低肥胖小鼠的肝重(1.24 g±0.03 g至1.08 g±0.04 g)、体重(32.46 g±0.50 g至28.35 g±0.58 g)和附睾脂重(1.33 g±0.13 g至0.81 g±0.08 g)及其与体重的比(4.06%±0.37%至2.83%±0.22%)。葡萄糖耐受实验和血液激素含量检测表明,丁酸钠部分缓解由高脂引起的葡萄糖不耐受,并显著降低血液中瘦素(3.71 ng/mL±0.62 ng/mL至1.50ng/m L±0.26 ng/mL)和胰岛素(2.39 ng/mL±0.30 ng/mL至1.25 ng/mL±0.09 ng/mL)的水平。肝中脂质和糖原的生化检测表明,丁酸钠对肝中的甘油三酯、胆固醇和糖原的含量没有显著影响。通过RT-PCR实验发现,丁酸钠显著上调线粒体β氧化和解耦联相关的关键基因以及线粒体自身编码的8个基因的mRNA水平的表达,Western印迹检测表明,丁酸钠显著升高肝葡萄糖转运蛋白GLUT2和调控线粒体功能的关键蛋白PGC-1α的表达。上述结果提示,丁酸钠可能通过增强肝线粒体功能缓解食源性小鼠肥胖。

Growth hormone and ghrelin secretion in severely obese women before and after bariatric surgery

Objective: The objective was to evaluate ghrelin and growth hormone (GH) interactions and responses to a growth hormone‐releasing hormone (GHRH)/arginine test in severe obesity before and after surgically‐induced weight loss. Research Methods and Procedures: Our study population included 11 severely obese women 39 ± 12 years of age, with a mean BMI of 48.6 ± 2.4 kg/m², re‐studied in a phase of stabilized body weight, with a BMI of 33.4 ± 1.2 kg/m², 18 months after having successfully undergone biliopancreatic diversion (BPD). A GHRH/arginine test was performed before and 18 months after BPD to evaluate ghrelin and GH interactions. Active ghrelin, measured by radioimmunoassay (RIA), and GH, measured by chemiluminescence assay, were assayed before and after the GHRH/arginine test. Results: Fasting serum GH levels and GH area under the curve (AUC) significantly increased from 0.2 ± 0.05 ng/mL to 1 ± 0.3 ng/mL (p < 0.05) and from 514.76 ± 98.7 ng/mL for 120 minutes to 1957.3 ± 665.1 ng/mL for 120 minutes after bariatric surgery (p < 0.05), respectively. Although no significant change in fasting ghrelin levels was observed (573 ± 77.9 before BPD vs. 574.1 ± 32.7 after BPD), ghrelin AUC significantly increased from ?3253.9 ± 2180.9 pg/mL for 120 minutes to 1142.3 ± 916.4 pg/mL for 120 minutes after BPD (p < 0.05). Fasting serum insulin‐like growth factor (IGF)‐1 concentration did not change significantly (133.6 ± 9.9 ng/mL before vs. 153.3 ± 25.2 ng/mL after BPD). Discussion: Our study demonstrates that the mechanisms involved in ghrelin and GH secretion after the secretagogue stimulus (GHRH/arginine) are consistent with patterns observed in other populations.     

Effect of culture medium on hydrogen production by sulfur-deprived marine green algae Platymonas subcordiformis

To study the effect of culture medium on hydrogen production by the marine green algae, Platymonas subcordiformis under sulfur deprivation, cell growth, hydrogen production, and starch and protein catabolism was investigated in the work. Algae cells cultured only in optimized medium required 6～8 days to reach the late logarithmic at the approximate density of (2.00 ± 0.18) × 10⁶ cells/mL, which in traditional medium needed 18～22 days to reach (1.85 ± 0.20) × 10⁶ cells/mL. Increased levels of Chlorophyll (10.74 ± 0.20 μg/mL), starch (149.50 ± 6.15 μg/mL), and protein (213.00 ± 7.36 μg/mL) were accumulated in optimized medium, which were 1.06, 1.47, and 1.87-fold of the algae cells cultured in traditional medium, respectively. The sealed culture of algae cells in sulfur-deprived optimized medium shifted to anaerobic conditions after 96 h of light illumination and produced 0.45 ± 0.12 mL H₂, but in traditional medium maintained aerobic condition and no hydrogen was produced. In addition, changes in starch and protein content during continuous light illumination indicated that more endogenous substrate was consumed in the sulfur-deprived optimized medium than that in the sulfur-deprived traditional medium.

Determination of trace cadmium in saliva samples using spray assisted droplet formation-liquid phase microextraction prior to the measurement by slotted quartz tube-flame atomic absorption spectrophotometry

BackgroundAn effective, green and rapid analytical strategy namely the simultaneous spray assisted droplet formation-liquid phase microextraction (S-SADF-LPME) method was developed for the determination of trace quantity of cadmium in saliva samples by using the slotted quartz tube-flame atomic absorption spectrophotometry (SQT-FAAS). By the developed method, external dispersive solvent usage for droplet formation was reduced to obtain a more environmental-friendly method.MethodsMethod consists of a simultaneous complexing and extraction step, which was based on spraying an extraction solvent containing a solid ligand into the aqueous sample solution, forming fine droplets without the use of dispersive solvent. The procedure was implemented using a customized, cost effective and portable spray apparatus to minimize the consumption of reagent, analysis time and operation steps. Thus, this methodology ensures better repeatability and accuracy while minimizing the relative errors caused by the experimental steps. Parameters including the buffer amount, extractant/ligand concentration, extraction solvent type, extraction/ligand solution volume, spraying number and vortex period were systemically optimized to lower the detection limit.ResultsUnder the optimal extraction conditions, 96.9-folds enhancement in the detection power of the traditional FAAS was achieved. The limit of detection and limit of quantification values of presented method were calculated to be 0.65 and 2.17 ng mL⁻¹, respectively. Accuracy and applicability of the optimized method was investigated by collecting saliva samples from smokers. Satisfactory percent recovery values wereachieved for cadmium with a low standard deviation in the acceptable range of 84.9–109.6 %.ConclusionThe developed dispersive solvent-free S-SADF-LPME technique presents a fast, simple, cost-effective and eco-friendly microextraction method based on the use of an easily accessible and functional spray apparatus.
